The Nineteenth Byte

12:12 PM

@Mayube As long as you don't stretch your experience / training too much, stretching your work time a bit like fudging with the dates a bit like Geobits said shouldn't be too much of a problem. If you stretch your experience too much they might put you in positions you can't actually do, but moving the dates a bit isn't much of a problem; they're usually too lazy to check those anyway.

(btw don't trust me on anything I say I'm in grade 10 and I have never had any work experience lol)

Mr. Xcoder

lol

Fatalize

@Geobits However, in the unlikely case that it is looked at again with slight scrutiny, you can be caught lying which is way worse.

Geobits

A family member of mine is the HR head at a decently sized company, and she's told me straight out they expect it from everyone. A resume is an advertisement, and they go shopping based on the ads. Unless it's something egregious (false diploma, fake company names, etc), they don't really care.

HyperNeutrino

mhm

I may specify that QFTASM and the computer from QFT cannot be used, though I'm not quite sure how to specify that

Geobits

Just pop this in the spec:

Mr. Xcoder

CMC: Given a String, check whether there are any two consecutive vowels (you may choose to handle what case you want, and up to you if y is a vowel or not).

"abcdeen" -> true (lowercase)

"FIY -> false (uppercase and y is not vowel in this example)"

HyperNeutrino

12:22 PM

Jelly: e€Øcẇ@11

Replace Øc with Øy to count yY

Erik the Outgolfer

@HyperNeutrino or e€Øc11ẇ

HyperNeutrino

oh right

nice

Geobits

12:24 PM

@Mr.Xcoder English, 37 bytes: Is any length-2 substring all vowels?

Mr. Xcoder

@HyperNeutrino How many history classes do you have in a week ಠ__ಠ \o

@Geobits ಠ____ಠ

Erik the Outgolfer

@Geobits umm, link to an implementation please? :p /s

Geobits

I am the implementation in this case. My eyes take input, my mouth output.

"abcdeen" -> yes

Mr. Xcoder

you multifunctional

Erik the Outgolfer

@Geobits what language are you implemented in???

Neil

12:27 PM

@Geobits 36 bytes: Is there a pair of adjacent vowels?

Mr. Xcoder

@EriktheOutgolfer In JS, he is a button, isn't he?

Geobits

@EriktheOutgolfer That's a detail which the user need not see or bother with.

HyperNeutrino

@Mr.Xcoder one every day

(gtg in a bit but not yet I guess)

Mr. Xcoder

@HyperNeutrino ಠ_ಠ Eugh

I would die if I'd have History each day

HyperNeutrino

lol

Erik the Outgolfer

12:27 PM

@Neil 26 bytes: Are there adjacent vowels?

HyperNeutrino

wait how does your hs work

what grade are you in

Mr. Xcoder

8th

Martin Ender

@Mr.Xcoder Slip, 4 bytes: `v`v (prints all pairs if any exist, and nothing if none exist)

Mr. Xcoder

We currently have 2 classes per week

@MartinEnder Wow, that's a language I've never heard of before... Nice I guess

Martin Ender

it's Sp3000's entry to the 2D pattern matching language design challenge (that was a long compound noun...)

Mr. Xcoder

12:30 PM

oh right, remember

Neil

1i`[aeiou]{2}

Mr. Xcoder

What language, regex?

:D

Neil

(outputs consistent truthy value and ignores case, can save bytes if not required)

@Mr.Xcoder Retina of course

HyperNeutrino

in our education system we have the same classes for the entire semester in different order, and then the next semester we take the other 4 classes (it's the semestered system; WCI implemented it two years ago)

Mr. Xcoder

@HyperNeutrino And (even better), from the 9th grade on we only have 1 history class per week :PP

Erik the Outgolfer

12:33 PM

@Mr.Xcoder in regex it would match 1i`+vowel+vowel

Mr. Xcoder

@EriktheOutgolfer That was a joke

Don't think it can get shorter in Pyth, 13 bytes: :w"[aeiou]{2}

HyperNeutrino

@Mr.Xcoder in 9th grade we don't even have history

Mr. Xcoder

Wow that's... strange... Different countries, different systems

HyperNeutrino

yup

we have canadian geo in grade 9 and canadian hist in grade 10

Mr. Xcoder

Our system is strange too.... Many, many quirks.

HyperNeutrino

12:38 PM

mhm

Erik the Outgolfer

do you have "final exams"?

Mr. Xcoder

@EriktheOutgolfer Describe them, to make sure we are talking about the same thing

Erik the Outgolfer

like, those in mid-may all the way to mid-june

HyperNeutrino

like the one that counts for like 30% of your overall mark

Erik the Outgolfer

I mean those that decide if you pass the class or redo later, and if you fail again you do the same class again

no 30% or anything now they are counted separately

Mr. Xcoder

12:41 PM

We have something called "final test", and you have to solve 3/4 (depending on the case) tests: maternal language, Romanian, Maths and either geography or history.

Erik the Outgolfer

"maternal language" ???

how's that?

Mr. Xcoder

@EriktheOutgolfer Mother's tongue

Erik the Outgolfer

I mean, they test it? like, what if your mother speaks chinese???

Mr. Xcoder

Like, if you're Turkish and live in Romania, you have to pass a turkish language test

HyperNeutrino

so in other words, no, romania does not have the same kind of final exams.

ASCII-only

12:42 PM

@EriktheOutgolfer Mother tongue...

HyperNeutrino

still is "final" but not the same exam type

Erik the Outgolfer

@HyperNeutrino yeah probably not

Mr. Xcoder

I mean those that decide if you pass the class or redo later, and if you fail again you do the same class again - One hardly ever redoes classes here, only extreme cases

Erik the Outgolfer

for example my mother is estonian that doesn't mean I have to learn estonian in my case

that's brutal...

Mr. Xcoder

@EriktheOutgolfer Mother's tongue means your primary language.

If you are English, say, and came to live in Romania, you get both a Romanian Language exam and an English exam (your main language)

Erik the Outgolfer

12:44 PM

but...but why should romania exam another language just because it's your primary language? I don't get it...

Mr. Xcoder

@EriktheOutgolfer Well we have lots of people from national minorities, some don't even speak Romanian well

HyperNeutrino

oh so is it partially to be able to pass by bypassing the romanian exam?

Mr. Xcoder

@HyperNeutrino Not really

HyperNeutrino

o

Mr. Xcoder

It's strange

Erik the Outgolfer

12:46 PM

and...if you're romanian that means you get a romanian exam and a romanian exam? :p

Mr. Xcoder

@EriktheOutgolfer They are merged, of course.

Erik the Outgolfer

heh

Mr. Xcoder

Like, if you don't speak Romanian too well because you're not born here, that test helps you improve your grade, rather than bypassing the Romanian examination

Erik the Outgolfer

I get that if you go to school in romania you should be at least trying to learn a bit of romanian (unless it's some "foreign school")

Mr. Xcoder

@EriktheOutgolfer Well the Romanian tests are more about the grammar or subtle literature quirks we have, it's hard if you "come from the outside"

Erik the Outgolfer

12:48 PM

"literature" oh that's tough

Mr. Xcoder

I like it

I dislike reading much, though

Erik the Outgolfer

I dislike reading at all :p

Mr. Xcoder

Well, I only do it if I have to too

Erik the Outgolfer

well, studying right?

Mr. Xcoder

yes

The only book I've read by myself (and really liked it) was Harry Potter :P

Erik the Outgolfer

12:51 PM

heh

Mr. Xcoder

Anyone up for a bit of JHT?

Erik the Outgolfer

not me I have to study in a while :(

Mr. Xcoder

sad

HyperNeutrino

I might be able to though depends on how long other people take to color in a map

(history = geography apparently)

(also it's a map of europe right pre-great war)

Mr. Xcoder

@HyperNeutrino Waiting for u, hopefully they will draw that map... in a preferable manner

*bad wording

HyperNeutrino

12:55 PM

well rip we're done with that

gtg now o/

Mr. Xcoder

Bye

ಠ_ಠ I'll have to go to my school every day for the next 2 months... ಠ_ಠ That includes Saturdays and Sundays

Erik the Outgolfer

why detention?

Mr. Xcoder

no

Saturday morning - Romanian Language "preparation" for an exam, Saturday afternoon - Maths "training", Sunday Morning up to Sunday Afternoon - Physics Hypertraining

Erik the Outgolfer

accelerated courses?

Mr. Xcoder

@EriktheOutgolfer kinda

Although not doing things in advance, just practicing more to get better

> a more succinct version of Jelly

Pfua :-) Is that a thing?

Erik the Outgolfer

1:01 PM

where?

Mr. Xcoder

@EriktheOutgolfer github.com/SatansSon/Levant

Erik the Outgolfer

it doesn't exist yet...

Mr. Xcoder

yes, but look at the description xD

Erik the Outgolfer

yeah it's a bit of a lie...it's not a language yet :p

Mr. Xcoder

Generally more succinct than Jelly is nearly a logical contradiction

Neil

1:04 PM

physics hypertraining? is that where hyperneutrinos come from?

Mr. Xcoder

@Neil No :P

Erik the Outgolfer

@Neil pun

@Mr.Xcoder if husk gets enough builtins I'm afraid it'll grow into power...

Mr. Xcoder

Well ATM it doesn't have enough built-ins

But when it comes to a more elaborate task, Jelly nearly always wins

if 05AB1E doesn't smash it, of course.

is it just me or 05AB1E used to be more competitive to Jelly in the past?

Neil

1:22 PM

@EriktheOutgolfer ugh, I wish the wiki had the atoms grouped by function

Erik the Outgolfer

jelly's?

Neil

yeah

but 05AB1E's too really

Erik the Outgolfer

not sure how that is possible

you mean the zip thingy?

Neil

right

J. Salle

@EriktheOutgolfer hey man can I ask you something about jelly?

Erik the Outgolfer

1:24 PM

what?

J. Salle

would Çn®¿ mean "repeat the last link while it's not equal to register" ?

Erik the Outgolfer

no

but Çn®$¿ would

(btw Ç actually means "link on line above")

J. Salle

yeah yeah that's what I meant by last link hahah, thanks man

HyperNeutrino

hi

J. Salle

Hello \o

HyperNeutrino

1:34 PM

o/

ooo jelly is happening

J. Salle

Yeah I'm trying to do something

and failing miserably while at it

HyperNeutrino

rip

what are you trying to do? I might be able to help

I see erik was teaching you some stuff earlier

also how does a qr code work? when it's scanned, does it just give text output?

Erik the Outgolfer

well he probably asked me because I have posted >400 answers in it?

HyperNeutrino

like what is its output format

@EriktheOutgolfer yeah true :P

Erik the Outgolfer

and found out I was active in here...

J. Salle

1:37 PM

@EriktheOutgolfer precisely

HyperNeutrino

@Neil ಠ_ಠ

J. Salle

I'm trying to do this codegolf.stackexchange.com/questions/143376/undress-a-string

HyperNeutrino

ah ok

J. Salle

Try it online! this is my code so far but it's obviously wrong hahahah

also rip html markups

Erik the Outgolfer

we use markdown not bbcode here :p

J. Salle

1:39 PM

yeah I noticed

Erik the Outgolfer

and your link is rip 404

J. Salle

should work now?

Erik the Outgolfer

yes

the catch is to remove only the spaces though

J. Salle

My biggest problem is that I have no idea how to use ifs in jelly

Erik the Outgolfer

oh it's simple if you get a grasp of quicks

it's (true)(false)(condition)?

J. Salle

1:41 PM

yeah exactly, I was trying to stop it when the string was equal to the register, which (I think) is the string without spaces

I can do it all on the same line?

Erik the Outgolfer

hmm...dunno tbh

J. Salle

I was thinking of trying to do something like "if input has leading whitespace, pop one" then "if input has trailing whitespaces, pop one"

mbomb007

RegexPlay: Test your regex skills. I did pretty good, and completed all 12 levels on intermediate. My score

4

J. Salle

But the atom reference page doesn't have much on whitespaces (or spaces in general)

HyperNeutrino

just pop a space and then reverse it

J. Salle

1:45 PM

I'll try that

Neil

took me 11 bytes just to remove a space if it begins with one: ṫ2Ṅ$¹ḣ1=” ?

Mr. Xcoder

yeah, ifs and Jelly are parallel

HyperNeutrino

Also 11: Ḋµ¹µḣ1Ḣ=⁶µ?

DJMcMayhem

Could you do something like (in pseudocode): concatenate(ternary(pop() == space ? nothing : the popped element))

HyperNeutrino

that would be slightly difficult

pop() gets rid of it so it would be hard to get it back

Erik the Outgolfer

1:52 PM

yeah you need register

HyperNeutrino

maybe with the register but I feel like that would be longer

(ninja'd >_<)

22 bytes, done

SPOILER Jelly, 22 bytes

still need 2 more bytes to beat 05ab1e

J. Salle

Based on Neil's code, would swapping ṫ for ḣ pop the last element if it is a whitespace?

DJMcMayhem

@HyperNeutrino Unless the ternary was it's own monadic link

HyperNeutrino

not sure what you mean...?

Mr. Xcoder

@HyperNeutrino Mhm, I feel like one of the µs is redundant

HyperNeutrino

1:56 PM

nope I tried taking them out

unless...

J. Salle

what does µ do? I haven't found it in the quicks or the atoms page

DJMcMayhem

@HyperNeutrino So write a link that uses a ternary: return z == ' ' ? '' : z then call that link with pop()

HyperNeutrino

yeah nope

@DJMcMayhem oh huh interesting idea

Mr. Xcoder

@J.Salle Starts a new monadic chain

HyperNeutrino

I feel like that'd be longer but I'll try it too unless you want to

Neil

1:57 PM

you see? it happened again

DJMcMayhem

@J.Salle it's under syntax, it means start a new monadic chain

Erik the Outgolfer

@mbomb007 parsing html with regex...mmm

Mr. Xcoder

See Syntax

Neil

I was using ṫ2 but Ḋ exists

DJMcMayhem

@HyperNeutrino I'm good (writing jelly from phone isn't a ton of fun)

J. Salle

1:58 PM

Thanks @Mr.Xcoder @DJMcMayhem

HyperNeutrino

ok

got 20 bytes now

DJMcMayhem

With my suggestion?

HyperNeutrino

no, I swapped ternary for repeat

I'll try yours now

DJMcMayhem

Ah

HyperNeutrino

I am now winning :3

uh how do you get an empty string in Jelly

Mr. Xcoder

2:00 PM

@HyperNeutrino “”

HyperNeutrino

oh nothing shorter?

darn it

DJMcMayhem

Isn't there a nilad?

HyperNeutrino

apparently not

there is []

Mr. Xcoder

there is I think

Erik the Outgolfer

you can use ⁸ but only if it's a nilad (i.e. no input)

Mr. Xcoder

2:00 PM

too lazy to search

HyperNeutrino

but that's almost never used because you almost always have a left argument

Erik the Outgolfer

@HyperNeutrino good luck typing that in jelly

HyperNeutrino

mhm why, does it not work?

Mr. Xcoder

@HyperNeutrino Alternatively, you can use ⁶Ḋ

HyperNeutrino

sure

Erik the Outgolfer

2:01 PM

@HyperNeutrino no

HyperNeutrino

but that's two links which is a pain so yeah empty string literal is still better

DJMcMayhem

In that case, my algorithm is almost surely longer. I thought there was a nilad for it

HyperNeutrino

oh rip

Erik the Outgolfer

but “” is exactly the same thing

ASCII-only

@mbomb007 RIP I tried hard lol play.inginf.units.it/#/end/1506001492845

2:03 PM

yeah @DJMcMayhem I think yours will be much longer

@J.Salle How are you doing on the string undressing challenge?

AdmBorkBork

@mbomb007 My results ... much better than I expected.

Neil

anyone got time for a stupid jelly question?

HyperNeutrino

2:13 PM

sure

Neil

let's say my main link is Ç that just runs the previous link as a monad, right

HyperNeutrino

yes

J. Salle

@HyperNeutrino not really well, and now my boss just came in so I'm not working on it atm

HyperNeutrino

@J.Salle ah okay.

Neil

and the value of that link is 0 on my given input

HyperNeutrino

2:14 PM

I can help with questions for the next while if wanted

Q: Undress a string

We already now how to strip a string from its spaces. However, as proper gentlemen, we should rather undress it. Undressing a string is the same as stripping it, only more delicate. Instead of removing all leading and trailing spaces at once, we remove them one by one. We also alternate betwe...

Neil

now Ḋ¹Ç? gives me different results to Ḋ¹0?. why?

HyperNeutrino

2:15 PM

@Neil 0 is a nilad and Ç is a monad.

caird coinheringaahing

@HyperNeutrino All I saw was "Jelly" :P

HyperNeutrino

@cairdcoinheringaahing ah ok lol :P

caird coinheringaahing

@J.Salle are you still learning Jelly?

AdmBorkBork

@cairdcoinheringaahing The CMC is the Regex challenge posted by mbomb007

HyperNeutrino

A monad will take the link before it and make it its argument. You'd have to place the argument explicitly before the link and possibly use the Nilad Link Quick after it.

J. Salle

2:15 PM

@cairdcoinheringaahing trying to, hahahah

caird coinheringaahing

@AdmBorkBork ಠ_ಠ I don't like regex :P

Neil

how on earth can you realistically use ? in that case?

AdmBorkBork

Neither do I

caird coinheringaahing

@J.Salle Have you applied to JHT?

@EriktheOutgolfer mhm lol

Neil

@HyperNeutrino Try it online!

HyperNeutrino

@cairdcoinheringaahing yeah I recall that rip :P (this is why I didn't actually send a link at all)

@Neil ḣ1=⁶ doesn't work

AdmBorkBork

2:20 PM

@HyperNeutrino String of whatever you want, afaik.

Neil

it returns 0

HyperNeutrino

@AdmBorkBork oh okay thanks. so it stores binary information?

@Neil yes because ḣ1 returns a list or something like that; it doesn't work

Erik the Outgolfer

@HyperNeutrino you would otherwise???

HyperNeutrino

@EriktheOutgolfer well not a real malicious link, no, just like a rickroll

AdmBorkBork

We have somewhere in the past a QR code generator where we put the PPCG logo and it generated a QR code that pointed to our website.

Neil

2:21 PM

ahh, so it's really [0]?

AdmBorkBork

@HyperNeutrino I'm not sure the exact encoding mechanism, but it's at a higher level than binary.

HyperNeutrino

@AdmBorkBork ah okay. I'm trying to make a challenge off of this for GoL so I need to know how the output should be given

@Neil yes, that's why it's always truthy :P

You could use Any and All, or you could compare to space and then do Head (Monad)

=⁶Ḣ$

(thanks to Erik for that trick)

caird coinheringaahing

@Neil FYI, you can append µŒṘ to the end of your program to see the actual version, rather than the Jelly version (which removes the [] around singleton arrays)

J. Salle

@HyperNeutrino I canibalized the 11 bytes you posted earlier and got to this: ṄḊµ¹µḣ1Ḣ=⁶µ?µṄṖµ¹µḣ1Ḣ=⁶µ?

HyperNeutrino

uh...what?

:P sorry I am somewhat confused by this

J. Salle

2:24 PM

Still need to repeat that until nothing happens

http://research.swtch.com/qr/show/5b8db625822b344e

HyperNeutrino

@J.Salle well no I mean that code looks quite ungolfed since it's practically the same thing copied twice. if only Jelly had an option for making a quick into an "object" and then call it so you could golf that

ÐĿ repeats until the results are no longer unique, and returns all of the intermediate results.

J. Salle

@HyperNeutrino just tried that, doesn't do what I need. I'm trying to golf it down a bit

HyperNeutrino

2:28 PM

okay

Neil

@HyperNeutrino well it's a bit late now but I got your original 22 bytes down to 18: Ḋ¹=⁶Ḣ$?UµÐĿ¹Ṛ2ƭ€QY

HyperNeutrino

@Neil Cool, thanks for the golfing anyway :D

Neil

@J.Salle you could probably use Ḋ¹=⁶Ḣ$? somewhere there

J. Salle

@Neil what does that do?

Neil

removes a leading space

J. Salle

2:30 PM

I'm currently trying to apply that same link to the reverse answer and then reverse it again

HyperNeutrino

If you have a link that removes a leading space and then reverses the string, you can just keep calling that until the result no longer changes

then reverse every other string to get the correct list

then remove duplicate elements (which are the result of having no more spaces to remove)

(oh wait that's my answer)

I'd like to see how your idea turns out though, so feel free to develop your approach!

Erik the Outgolfer

gtg bye

Neil

speaking of which, why are you inconsistent in your use of U and Ṛ?

caird coinheringaahing

o/

Conor O'Brien

I'm trying to compile a list of languages that "win" code golf the most. has this been done before?

Neil

2:33 PM

also the µ starts a new chain, so probably shouldn't be after a link in an explanation

caird coinheringaahing

@Neil U reverses each element in the array, but Ṛ reverses the whole array

HyperNeutrino

@Neil uh not sure, too lazy to change it now though

@Neil that's true, but I use µ...µ to denote a link which isn't technically correct as people with experience in Jelly will notice, but makes more sense (I think and hope) to non-Jellyers

technically I could use U or Ṛ in both cases so I really don't know what I was thinking

caird coinheringaahing

@HyperNeutrino -1, U is better (no copy paste needed) :D

HyperNeutrino

that's why I usually use U

Neil

@HyperNeutrino there is only one µ in your answer...

HyperNeutrino

2:35 PM

I used to have compose key but my new Linux account doesn't seem to work with that

@Neil wait really? that is odd

oh right

yeah I'll change that I guess

@HyperNeutrino Yep :P

Also, I'm really sad that ŒĐ doesn't do anything in Jelly.

Poke

why does ^(?=\d{1,3}\.\s)[A-Z] not match 123. X

i think i fundamentally misunderstand lookaheads

caird coinheringaahing

@Poke Just a guess but isn't ^ the end of a line?

Poke

2:38 PM

$ is eol iirc

Conor O'Brien

^

HyperNeutrino

$

caird coinheringaahing

ಠ_ಠ Yeah, I don't know regex :P

Conor O'Brien

you know how a positive lookahead works?

Neil

the lookahead matches the 123. but doesn't advance the match

Conor O'Brien

2:40 PM

^[A-Z](?=\d{1,3}\.\s) matches X123.

Neil

so the [A-Z] tries to match at the start too

Conor O'Brien

e.g.

Neil

@ConorO'Brien strictly speaking, it matches a leading X that is followed by 123.

Conor O'Brien

yeah

Poke

right that's what i'm seeing

how do i advance the match

Neil

2:44 PM

just don't look ahead

Poke

rather advance the cursor without advancing the match

i only want to match the X

Neil

if your regex flavour supports it, lookbehind

and it's variable too, so good luck with that

I know .NET regex can do that at least
